Sensor fault detection and diagnosis using zonotopic set-membership estimation [PDF]

22nd Mediterranean Conference on Control and Automation, 2014
This paper proposes new sensor fault detection algorithms for linear discrete-time systems with bounded perturbations and bounded measurement noise. This fault detection technique is based on a zonotopic set-membership estimation method. The first proposed fault detection algorithm allows to detect the presence of a fault. A second algorithm leading to
